CARBONATOR.

Patented Nov. 1e, 1907.

Application filed January 15. 1904. Serial No. 189.186.

` To all whom fit may concern:

Be it known that 1, EDWARD E. MUR'PHY, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Carbonators, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The presen-t invention relates to a carbonator of that type in which plain water is pumped into a carbonator chamber which also receives gas, the gas and water being mixed inthe chamber, and the chamber supplied with water and gas to maintain the supply of `carbonated water.

The invention relates mainly to a novel construction and arran ement whereby the mixing of the water an the as is. rendered more` thorough, the water cmg sprayed through the gas in the chamber and collected in a mixer which is open at the top and closed at the bottom, in which the water and vgas become thoroughly mixed, and from which the carbonated water overflows into 'thelmain body `of the carbonator chamber.

' through the gas in the chamber, thus mingling with the gas and carrying it into the mixer which concentrates the water and brings it into intimate union with the gas carried along with the water, the thoroughly carbonated water finally filling the mixer and overflowing from the top thereof. As herein shown, the mixer is further provided with a coarse strainer across the top, which assists in the mixing process, and the water inlet, which is directly over the middle of the mixer, is arran ed to spread the Figure 1 is a vertical section through the middle of"a carbonator embodying the invention, at the top of the carbonator chamber; and Fig. 2 is'a detail showing a lan View of a portion of the spraying nozz e.

The chamber a, which may be supplied with gas in any suitable or usual way, is provided at the top with an inlet b2 for water,

l which inlet is so arranged as to cause the water to be converted into'spray as it enters the chamber.

As herein shown, the inlet b2 is formed in a member, b which is connected by means of a coupling piece c2 with a tubular member c having a ange c3 and nut c", by means of which it is clamped in an opening in thetop of the carbonator chamber aa. The said member c also affords a support for the spraying device which consists of a tubular member d which is supported within the member c, and which contains a strainer d2, below which is a disk d3 having a series of inclined openings d* (Fig. 2) through which the water passes into a cup-shaped member d5 having an opening al through the middle. The member d5 is shown as screw-threaded upon the end of the member d, and provided with shoulders between which and the end of said member is clamped the disk d3.

The water forced in through the inlet b2 passes downwardly through the channel b3 into the member d, through the strainer d2, and, in passing through the inclined openings d, is forced tangentially against the curved inner surface of the' member d5, thus acquiring a whirling motion, so that it passes through the outlet d in a thin, cone-shaped spray which spreads towards the edges of the mixer e which is supported within the carbonator chamber a, directly below the inlet. The said mixer e is closed, except at the top, and is shown as shaped like a pot or cup, and provided with an annular rim e2 to.l which are connected arms e3 which, in turn, are secured in a nut e4 which is threaded upon the lower extremity of the member c which is in the interior of the carbonator chamber a. The spray entering the chamber a passes through the atmosphere of gas therein, a portion of which gas is carrled along with the spray into the mixer, the direction of the spray being such that in the beginning it impinges a ainst the interior walls of the mixer e an the gas becomes intimately mixed with the water as the latter fills the mixer. When the mixer has become filled to overflowing, the spray passing through the gas above the mixer entrains the-gas and carries it down into and through the water in the mixer.

perfect admixture of the gas and water, the mixer e may be provided with a strainer e5, herein shown as a net-work of coarse wires extending across the top of said receiver and held in place by means of a ring e which may be soldered, or otherwise secured, to the annular membereg. The mixer e is preferably substantially hemispherical in shape, so that the gas and the spray forced into the wat-er inthe mixer are brought into smaller compass as the force of the spray is overcome by the resistance of the water, which bottom, and lateral outlets e9 for the gas near the top of the mixer. This provides for an atmosphere of gasvwithin the conical sheet of spray, so that a full volume of gas meets the surface of the sprayed water at both sides. As herein shown, the said pipe e7 is closed at the top, and provided with a conical deflector el to keep the water away from the lateral outlets e".

The inlet passage b3 may be provided with a valve b3, herein shown as mounted on a threaded stem, projecting through the member bal, threaded in the top offthe member b, the said stem extending through a packing gland b, and having a handle 1133 for opening and closing the valve. This valve is provided merely r the purpose of closing To assist in breaking up the spray, and 1n causing a tom and being substantially hemispherical in shape and substantiallyl larger in diameter than the s raying device, to receive the water admitte through the spraying device anda coarse strainer across -the top of the receptacle, substantially as described.

2. In a carbonator, a receptacle provided at the top with a spraying device having inclined openings and a cup-shaped member havin an opening vthrough .the middle,

where y a cone-shaped spray is obtained;

a mixing receptacle suspended Within the main receptacle below said spraying device, said mixing receptacle being substantially hemispherical in shape and closed at the bottom and open at the top the opening at the top being substantially larger in diame-v ter than the spraying device; and a pipe projecting upward through said mixing receptacle and provided at the top with a conical deilector and one or more lateral ducts or assages, substantially as described.

n testimony whereof, I have signed my name Ato this specification in the presence of Atwo subscribing Witnesses.
